In 2023 there was also massive fires in Canada covering a similar area, 2021 Siberia, in 2019/2020 in Australia, 2015 in Indonesia (peat fires, less area but similar emissions)... there is a long list of extended fires with weighty emissions all in the last decade that nullifies and add a big share to every trial of forestation as natural carbon capture method. And things will get worse as that is in part a positive feedback loop.

Australia has long had fires. Fires are an integral part of Australia’s historic natural environment.

So much so, that Eucalyptus trees evolved to become a fire dependent species that benefits from regular burning. This is why they are so dangerous when planted in places like Los Angeles.

I’m not meaning that ocasional/limited forest fires can or not be healthy for forest. Just that the mentioned ones were all record breaking, and had a significant contribution to long lasting CO2 in the atmosphere, all of them were in similar orders than the 2024 fires.

And that carbon capture through planting trees may be something fragile and short lived.

The 2019–2020 fires were so hot that eucalyptus trees actually struggled to reproduce. Trees with pyrophilic seeds that normally like a good scorching were instead totally consumed by the fires, and the soil got so hot that seeds already dropped and buried were burned to death. Trees that store energy in their wood (either underground or shielded by bark) got so hot that their normally safe wood burned.

Obviously not every tree died due to the fires, but the death and destruction left in the wake of this fire was on a scale far surpassing past fires. Not to mention the deaths of animals.
